INTRODUCTION Waste electrical and electronic equipment Improperly disposed electronics Includes electronic products such as computers, computer peripherals,televisions,VCRs,DVD,Players,stereo equipment, hand cell phones etc. E-waste contains harmful toxic substancesImport of e-waste developed countries to developing countries
HAZARDOUS ELEMENTS IN E WASTESulphurLeadBerylliumLeadBariumCadmiumMercury
• Cadmium: The most common form of cadmium is found in Nickel-cadmium rechargeable batteries. The inhalation of cadmium can cause severe damage to the lungs and is also known to cause kidney damage.• Lead and beryllium oxide: the are used as solder and thermal grease respectively and are both harmful and cause severe lung infections.
Material composition of personal computersOTHER(includes lead, mercury, copper, zinc and cadmium) Aluminium Ferrous metal Silica/glass Plastics 17% 23% 14% 26% 20%
ISSUES AND PROBLEMS• Rapid changes in technology• Changes in media• Falling prices• Developing new electronics and discarding old ones• Technical solutions are available, but in most cases a legal framework, logistics• And other services need to be implemented before a technical solution can be applied
E-WASTE INDIAN SCENARIOE- waste market is unorganizedMunicipal wasteUnskilled workers, absence of adequate technology, improper handlingMore focused on profitNo mechanism to check the flow of E- waste0.1-0.2% municipal wasteBusiness accounts for 78%800000 tone E- waste is generated in 2012Sale of computer & laptop has been grown 18% in 09-10Self organizedReasons for E- waste generation
WHY IS E-WASTEGROWING ?Industrial revolution followedby the advances in informationtechnology during the lastcentury has radically changedpeoples lifestyle. Although thisdevelopment has helped thehuman race, mismanagementhas led to new problems ofcontamination and pollution.The technical prowess acquiredduring the last century hasposed a new challenge in themanagement of wastes.
Growing ECE Industry in India Information and telecom fastest growing industry verticals PC sales crossed 7.3 million units in 2007-08 growing 16%; installed base of over 25 million units Consumer electronics market growing at 13-15% annually ; 120 million installed base of TVS Cellular subscriber up by 96.86% over last year; Installed base to cross 300 million by 2010
VOLUME OF E-WASTE•An estimated 50 million tons ofE-waste are produced each year.•The USA discards 30 millioncomputers each year and 100million phones are disposed ofin Europe each year.• The Environmental ProtectionAgency estimates that only 15-20% of e-waste is recycled, therest of these electronics godirectly into landfills andincinerators.
HOW E-WASTE AFFECTS OUR HEALTHSeveral health issues associated with the toxins found in the e wasteDamages kidney & liverCause retardation, high blood pressureDisrupts endocrine system functionsCause eye and throat irritation
HOW E-WASTE AFFECTS OUR ENVIRONMENT? It has become a uncontrollable issue Contaminated leachates pollute the ground water Uncontrolled burning and disposal are environment problems Causes acidification of soil Not only leaching of the mercury poses serious problems
RECYCLINGKey components of modern waste reductionThird component of the “reduce,reuse,recycle” waste hierarchyISO standards relating to recycling; ISO 15270:2008 - Plastic waste ISO 14001:2004 - environmental management control of recycling practiceRecycling consumer waste • Collection • Drop-off centers • Buy-back centers • Curbside collection • Sorting
BENEFITS OF RECYCLINGEffective solution to the growing e-wasteproblem Reduces the amount of green gas emission Pollution caused by hazardous disposal isavoided
CONCLUSIONWHAT CAN CONSUMERS DO? Keep your old electronics longer instead of replacing them If discarding old electronics, be sure to recycle them at a trusted recycling center Purchase electronics that do not contain hazardous materials
WHAT CAN PRODUCERS DO? Extended producer responsibility Design for environment Take back offer & incentives
